Although there is no limit to the seeds planted, there will still be pests and drought.
So I'm going to disclose this method now:
Step 1: Click on the Home Warehouse (please confirm that the home is the anniversary background).
Step 2: Choose the background of Momo Plain.
Step 3: When changing the background, don't save it, just plant seeds in it.
Step 4: Click Refresh to refresh the page without saving the seed (or press F5).
Step 5: When you log in again, you will find that there are seeds on the ground in your home. ...
Step 6: Click "Home Warehouse" again.
Part VII: Keep the seeds where they can be planted under normal circumstances.
Step 8: Water the seeds.
Note: When changing rooms, make sure there are no seeds in the field, otherwise there will be none.
That's what I did. It really works. At first, I saw someone else's house and asked him if he didn't tell me, but this method didn't work since May 8.
